- ben_w 5y agoI’m not saying he’s wrong — I have neither the education nor the experience nor the time to do so — but as a word of caution: One single atom in a different place, or a chiral flip of the molecule as a whole, can radically change the biological response of a chemical. H2O is good; remove one atom, get explosive H2; add one atom get the bleach H2O2. For chirality: S-penicillamine is an anti-arthritic, R-penicillamine is highly toxic[0] (I was going to use thalidomide as my example, but that turns out to be something which changes between both chiralities inside your own body).
